Quality and other technical information related to this item:

1993

Although the intent of this question was to capture directly funded work, it appears some academics
and consultants whose work was not directly funded considered their work "supported" if the
university or company at which they worked received a federal grant. Item nonresponse was
moderate for the SDR (9.0 percent) and low on the NSRCG (less than
1.0) and NSCG (1.6 percent).

General

In 1993, 1995 and 1997, this question referred to work supported during the week of April 15 of
the reference year. In 1999, this question referred to work supported in 1998, the previous full calender
year. Additionally, this question was only asked on the SDR in 1999. Please note these differences
when making comparisons of the data between 1993, 1995 or 1997 with 1999.
